Definitions

  • the invention relates to a color changer comprising a valve module having a first interaction surface, a plurality provided in the valve module valve means which are connected at their respective inlet side with a respective supply channel and at their respective outlet side with a common collecting channel, wherein the valve means via respective switching means with a respectively in a switching module having a second interaction surface and exactly one actuator, which opens with a second actuation end in the second interaction surface, valve module and switching module with their respective interaction surfaces adjacent and are arranged along this against each other slidably and wherein by a respective sliding movement, the second operating end at the same time a maximum of one of the first operating ends in a respective operating position bewegb ar is, so that an opening and closing of the respectively associated valve means is made possible by exactly one actuator.
  • a variety of different shades are used in industrial painting, for example, in paint shops for automobile bodies or attachments.
  • Such paint shops are mostly robot-based and designed at typical cycle times of 60s to 90s to paint a different color in each cycle, with 20 to 60 different colors in the automotive industry is a common number.
  • one each To supply supplied to a robot arm atomizer with a paint material of the desired color usually color changer are provided. These have a plurality of inputs for paint material, which are connected to corresponding supply lines for the different paint materials.
  • the paint materials are usually provided by means of so-called ring lines at various delivery points along the painting and provided from there by means of the supply lines to the respective color changer.
  • a color changer usually has a common collecting channel, in which the supply lines open at least indirectly, the output of which is connected via a line to the atomizer to be supplied with paint material.
  • Valve means are provided between the respective inputs of the color changer and the common collection channel. Depending on which of the valve means is open, the corresponding paint material is introduced into the collecting channel during painting and forwarded from there to the atomizer. At least one input of a color changer is usually connected via a valve means with a solvent line in order to clean in the case of a color change the collecting channel for the next paint material with a different hue. Frequently, cleaning also involves the feeding of an air / solvent mixture which is produced by alternating, pulsed feeding of air and solvent. The cleaning effect of such a mixture is significantly increased with reduced solvent consumption.
  • Valve means are subject to wear and thus leakage may occur over time. If a valve means no longer closes reliably, so marginal amounts of a paint material of a first hue can get into the collection channel despite actually closed state of a valve means and mix with a paint material located therein a different hue.
  • the basic idea of the invention is, on the one hand, to physically exclude a simultaneous actuation of a plurality of valve means and, furthermore, to visually make visible a possible leakage of valve means as clearly as possible.
  • a drive device is ideally provided, for example one or more stepper motors or pneumatic actuators.
  • the second actuation end of the exactly one actuator is simultaneously positioned opposite at most one of the first actuation ends, in which position an interaction of the respective actuation ends is made possible.
  • the actuating ends preferably act perpendicular to the respective interaction surfaces, for example in the form of a joint push or pull movement. But it is also possible that the respective actuating ends comprise lines which are hermetically connected to each other in the operating position. Thus, it is also possible, for example, to direct a compressed air from the actuator through the conduit thus formed from the switching module in the valve module and thus to effect a switching of a respective selected valve means.
  • the interaction surfaces are at least partially opposite one another and arranged displaceable or movable relative to one another.
  • the interaction surfaces it is possible both for the interaction surfaces to adjoin one another directly, that is for them to be slidably movable on one another, but also for the interaction surfaces to be arranged at a distance from one another, for example 1-2 cm.
  • the gap existing in this case is then to be bridged by the actuating ends, at least in the case of actuation of a respective valve means, which then correspondingly protrude from the respective interaction surface.
  • all first operating ends of the switching means protrude in the closed state of the first interaction surface.
  • the first switching ends in the first interaction surface is also advantageously allows that in the case of a possible leakage of one of the valve means leaking paint material preferably collects on the first interaction surface and thus is particularly quickly visible, so that any leakage in an advantageous Way is easy to locate.
  • the switching means provide a preferably mechanical operative connection between their respective first switching end and the valve means to be switched, for example in the form of a push rod or the like.
  • the push rod is then optionally connected with its side remote from the operating end directly to the valve means and thus actuates this as needed.
  • An actuator is preferably designed to perform a linear movement. In the case, that an actuator is able to exert a force only for one of its two directions of movement, are provided either in the actuator itself or in the switching means corresponding spring elements, so that a provision of the actuator is effected by a spring force.
  • the valve and the switching module are movable relative to each other about a common axis of rotation, wherein the first actuating ends of the switching means are arranged along a circular path about the axis of rotation.
  • the common collecting channel merges at its first end into an outlet channel.
  • appropriate connection means are provided at the first end of the collecting channel or at the outlet channel, for example a respective screw connection as a transition to a hose.
  • a hose connection is then guided directly or indirectly to a respective atomizer, which is then mounted, for example, on a robot.
  • an inlet channel opens into the second end of the common collecting channel, which is provided for the supply of air and / or cleaning agent.
  • an inlet channel By fluidly provided at the beginning of the common collecting channel junction can be cleaned from its second end to the first end in the event of a color change after closing all the valve means the entire collecting channel and be prepared for a next color.
  • a corresponding inlet valve for air and / or cleaning agent also actuated by the exact one actuator, so that a common opening of a valve means for color is excluded together with the inlet valve for air and / or cleaning agents.
  • separately openable and closable further valve means are provided for the inlet channel and / or in particular the outlet channel.
  • a flow of color to the atomizer can be interrupted in an advantageous manner, for example to allow the lacquer material to be pressed on or else to enable a synchronous switching of the color flow in accordance with the requirements of a lacquering program of a robot.
  • the valve module and the switching module are designed and cooperate in such a way that the valve means are closed in the unactuated state.
  • spring elements are preferably provided, which press the valve means in the idle state in the safe closed state. In the case of an actuation of one of the valve means by the exactly one actuator, this optionally brings a force acting against the spring force and thus causes an opening of the respective valve means selected.
  • the switching means are designed such that opening of a respective valve means is effected by a return movement of the second actuating end of the actuator into the second interaction surface. This either requires that the respective first actuating end of the respective selected switching means presses with a spring force against the second actuating end of the opposite actuator or that coupling means are provided between the second actuating end of the actuator and the respective first actuating end, by which the transmission of a tensile force is enabled.
